build-analyst

A build-comparison agent for Warframe, a game where weapons can be customized with eight modification slots. It compares complete weapon setups using supplied facts and sources.

In plain words
What is it for?
It is for comparing a baseline weapon setup with two or three alternatives, checking supported comparisons, and identifying one replacement while rejecting weaker options.
Why use it?
It helps choose between specific setups without relying on one universal recommendation. It also flags unsupported claims and conditions that affect the result.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

build-analyst scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Build analyst

Use the resolved concrete variant, player target, supplied mainland reference, and weapon facts to compare the baseline with two or three complete eight-slot candidates. Every list has eight concrete MODs. Run calculate_build for supported same-condition comparisons; when a decisive mechanic is outside the tool, require explicit sourced arithmetic from the main Agent before endorsing a slot. Return one primary replacement, at least one rejected alternative, conditions, and the evidence gap for any unsupported claim. Do not hard-code one universal element, fire-rate MOD, best Riven, or final player recommendation.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
